Support for heterogeneous database artifacts in a single project

ABSTRACT

A single software project can include heterogeneous types of artifacts. The artifact definition can be converted to a format compatible with a common model or information derived from the artifacts can be added to the common model so that tools that operate on the common model can provide information derived from the heterogeneous artifacts to developers during design time in an IDE. Build and deployment tools can operate over a more inclusive universe of data to provide a more accurate deployment plan. Build and deployment tools can operate within the context of the IDE or from the command line.

BACKGROUND

An integrated development environment (IDE) is a software application that provides functionalities for software development. An IDE, also sometimes called an integrated design environment or integrated debugging environment, typically includes a source code editor, a compiler and/or an interpreter, build automation tools and a debugger. Some IDEs include a version control system. An IDE can also include tools used for development of object-oriented software including but not limited to a class browser, an object inspector, and class hierarchy visualization tools. Other tools can also be included in an IDE.

An IDE is designed to increase developer productivity by providing integrated components that usually have similar user interfaces to reduce the learning curve. Typically an IDE is dedicated to a specific programming language, so as to provide a feature set which most closely matches the programming paradigms of the language. However, some multiple-language IDEs are in use, including Eclipse, ActiveState Komodo, NetBeans, Microsoft Visual Studio®, WinDev, and Xcode.

Known IDEs do not support heterogeneous database artifacts within the same project. For example, a developer who uses Microsoft's Visual Studio® has to keep T-SQL artifacts in one Visual Studio project, XSD artifacts in another Visual Studio project, C# SQL CLR artifacts in a third Visual Studio project and VB.NET SQL CLR artifacts in still another Visual Studio project. This is true because the languages behind each of the different kinds of artifacts is different. Because the languages behind the different types of artifacts is different, supporting a seamless developer experience when moving from one language to another language is difficult. Because editing tools including but not limited to auto-completion, debugging and refactoring tools typically do not cross project boundaries, these tools do not provide comprehensive information to the developer when a solution includes multiple project types. Other tools such as tools for automated deployment may generate incorrect deployment plans because they are operating on a subset of the actual data.

SUMMARY

An IDE can provide integrated software development tools to create and manage database artifacts for a plurality of types of database artifacts by incorporating information associated with the heterogeneous types of database artifacts into a common model within a single software project. Heterogeneous language services can be hosted within the same project, enabling different language-specific editing experiences to be provided within a single project. Tools that operate on the common model can include tools for creation and management of the database artifacts, tools that provide auto-completion and member lists for the database artifacts, tools for refactoring the database artifacts, tools for debugging the database artifacts and tools for deployment of the software project. Different types of artifacts can be stored in the same project and information associated with the artifacts can be stored in a common model. The information stored in the common model can include definitions of model elements and relationships between model elements. This enables various types of database artifacts to exist in the same project and to be correctly processed by program development tools. For example, a T-SQL file can be interpreted and database elements created when the T-SQL file is executed can be added to the common model, an XSD file can be determined to be a part of an XML Schema Collection and the schema collection definition can be added to the common model and/or a program file can be compiled into an executable (e.g., compiled into an assembly as a SQLCLR artifact) and definitions found in the executable can be added to the common model.

This Summary is provided to introduce a selection of concepts in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

DETAILED DESCRIPTION

Overview

A single software project within an IDE can include heterogeneous database artifacts including but not limited to T-SQL, XSD and program code such as but not limited to VB.NET and/or C# code. T-SQL files can be interpreted or analyzed and information derived from the interpreted or analyzed files can be added to a common database schema model. XSD files can be wrapped in a T-SQL XML Schema Collection CREATE statement and can be added to the common database schema model. The XML Schema Collection schema can be extracted, added to the common model and can be used in the database for creating database table columns having that schema. Language files can be compiled into an executable such as but not limited to a dll, an assembly (e.g., in MSIL Microsoft Source Intermediate Language) or can be interpreted into bytecode, etc. The assembly, bytecode or executable can be wrapped into a valid T-SQL statement and can be added to a database such as a SQL database. Information derived from the compiled or interpreted code can be added to the common model. For example, definitions for public types found in the assembly can be added to the common model enabling stored procedures in the project to call the public types.

Because model elements including artifact definitions and relationships between model elements are located in one common model, heterogeneous language services can be hosted within a single project. This enables a user to switch language services (e.g., from C# to VB.NET or vice versa) without closing one project and opening another. Refactoring can operate on the entire database schema. When, how and what needs to be refactored can be determined. A particular refactoring operation can be driven by the appropriate language service in the project. For example, if a C# artifact needs to be refactored, the refactoring task can be delegated to the C# language service. Auto-completion tools such as but not limited to Microsoft's IntelliSense® can draw from heterogeneous artifacts including but not limited to T-SQL, XSD and SQL CLR constructs to provide robust auto-completion feedback during design time development. A seamless cross-language debugging experience can be provided to the developer or user. For example, if a developer in a debugging session steps into an XML Schema Collection or steps into an XPath query, the associated XSD source code can be displayed in the same debug session in which a C# program was debugged without initiating a new debugging session or closing one project and opening another. Build tasks that are not capable of working on multiple projects, have access to the entire database schema instead of having access to a subset of the database schema, allowing for creation of a correct database deployment plan.

Support For Heterogeneous Database Artifacts in a Single Project

FIG. 1 a illustrates an example of a system 100 for supporting heterogeneous database artifacts in a single project 106 of an IDE 104. All or portions of system 100 may reside on one or more computers such as the computers described below with respect to FIG. 3. All or portions of system 100 may reside on one or more software development computers such as the computers described below with respect to FIG. 4. The system 100 or portions thereof may comprise a portion of an integrated development environment (IDE) such as the ones described and illustrated below with respect to FIG. 4. System 100 or portions thereof may be provided as a stand-alone system or as a plug-in or add-in.

System 100 may include one or more of a computer 102 comprising: a processor such as processor 142, a memory such as memory 144, and one or more modules such as module 108, etc. for supporting heterogeneous database artifacts in a single project. Other components well known in the arts may also be included but are not here shown. It will be appreciated that one or more modules such as module 108, etc. can be loaded into memory 144 to cause one or more processors such as processor 142 to perform the actions attributed to the one or more modules for supporting heterogeneous database artifacts in a single project.

In operation, artifacts including but not limited to T-SQL artifacts such as T-SQL artifact 118, XSD artifacts such as XSD artifact 122, program language artifacts such as a VB.NET and/or C# artifact 120 and other artifacts 124 can be created and managed in the IDE 104 as is known in the arts. A module such as module 108, etc., can receive these artifacts and transform information derived from the artifacts into a common model 110. A module such as module 108, etc., can derive information from these artifacts and add the information derived from the artifacts into a common model 110. For example, a T-SQL file in which a new table is created can be examined and in response to determining that the new table is created, a definition for the new table can be added to the common model 110. Module 108, etc. can receive the artifacts and can convert the artifacts into a valid T-SQL statement, as described more fully below. Placement of the various artifact definitions and relationships between artifacts in a common model (e.g., common model 110) enables information about the objects including but not limited to types, names, dependencies, validation rules for values for the object, physical location, relationships between objects and so on to be available to the tools in the IDE. For example, when a developer performs an operation on an object in the project, relationships between the object and other objects can be traced and information associated with the relationships can be displayed to the developer. For example, in response to an operation renaming an object called “AddressID” to “MyAddress”, relationships can be traversed so that all the code affected by the operation can be displayed and changed.

One type of artifact received by module 108, etc. can be a Transact-SQL (T-SQL) artifact. T-SQL is a proprietary extension to SQL. SQL, Structured Query Language, is a database computer language designed for managing data in relational database management systems (RDBMS). A SQL database can include tables, views, programmability objects, security objects including but not limited to logins, management objects (e.g., what disk drive to use for the database) and so on. SQL includes programming constructs for data insertion, query, updating and deletion, schema creation and modification, and data access control. T-SQL can be used with Microsoft's SQL Server software. Applications that communicate with an instance of SQL Server communicate by sending T-SQL statements to the server, regardless of the user interface of the application. T-SQL augments SQL with additional features including but not limited to control-of-flow language, local variables, various support functions for string processing, date processing, mathematics, etc., changes to DELETE and UPDATE statements and so on. In accordance with aspects of the subject matter disclosed herein, a T-SQL artifact 118 can be interpreted and added to a common database schema model such as common model 110. For example, the text of a particular T-SQL artifact may create a new database table and describe its contents. The T-SQL artifact can be interpreted to determine the name and attributes of the table and the common model can be updated with the information about the new table.

In SQL Server, the ability to create XML Schema Collections exists. XSD (XML Schema Definition) is the schema language of the World Wide Web Consortium (W3C), an international standards organization for the World Wide Web. The consortium is made up of member organizations that work together to develop standards for the World Wide Web. XSD is one of several XML schema languages. The acronym “XSD” is sometimes also used to refer to XML Schema Document, a document written in the XML Schema language, typically containing the “xsd” XML namespace prefix and stored with the “.xsd” filename extension. The XSD schema language is sometimes referred to as WXS, an acronym for W3C XML Schema. XSD can be used to express a set of rules to which an XML document has to conform in order to be considered “valid” according to that schema. However, unlike most other schema languages, XSD was also designed with the intent that determination of a document's validity would produce a collection of information adhering to specific data types. Such a post-validation information set can be useful in the development of XML document processing software.

XSD artifacts such as XSD artifact 122 can be received by a module such as module 108, etc. Module 108, etc. can wrap the XSD file in a T-SQL XML Schema Collection CREATE statement (fragment), enabling the XSD artifact to be added to the database. An example of an XSD file 250 is included in FIG. 2 a. The XSD file 250 is wrapped in the T-SQL XML Schema Collection CREATE statement 252. The schema 254 can be extracted and placed into the common model 110. XSD may also drive how information in Microsoft's IntelliSense® is presented to the user. For example, the Visual Basic Code Editor includes IntelliSense features for XML that provide word completion for elements defined in an XML schema. If, for example, an XML Schema Definition (XSD) file is included in a project and the user imports the target namespace of the schema (e.g., by using the Imports statement), the Code Editor can include elements from the XSD schema in the IntelliSense list of valid member variables for XElement and XDocument objects.

SQL CLR (SQL Common Language Runtime) is a technology for hosting of the Microsoft .NET common language runtime engine within SQL Server. The SQL CLR allows managed code to be hosted by, and run in, the Microsoft SQL Server environment. SQL CLR allows users to create managed code objects in SQL Server in .NET languages including but not limited to C# and/or VB.NET. The managed code objects in SQL Server can include but are not limited to: stored procedures, analogous to procedures or void functions in procedural languages like Visual Basic or C; triggers, stored procedures that fire in response to Data Manipulation Language (DML) or Data Definition Language (DDL) events; programmability objects including but not limited to user-defined functions (UDFs), analogous to functions in procedural languages; user-defined aggregates (UDAs), allowing developers to create custom aggregates that act on sets of data instead of on one row at a time; and user-defined types (UDTs), allowing users to create simple or complex data types which can be serialized and deserialized within the database. The SQL CLR relies on the creation, deployment, and registration of .NET assemblies, which are physically stored in managed code dynamic load libraries (DLLs). These assemblies may contain or include .NET namespaces, classes, functions and properties. Program code (e.g., the dll, assembly, etc.) can be wrapped in a T-SQL statement and added to the database in the project.

It will be appreciated that while particular examples of input to module 108 have been described, other inputs are contemplated. For example, SQL artifacts or artifacts written in another database computer language (e.g., artifacts written in Javascript for an Oracle database) in addition to or instead of T-SQL artifacts can be received. Similarly, in addition to or instead of XSD artifacts, artifacts in another schema language can be received. Similarly, in addition to or instead of receiving program modules written in a managed code language such as VB.NET or C#, program modules written in other managed code languages including but not limited to F#, dylan.NET, COBOL, Perl, Python, Eiffel and so on or in other compiled or interpreted native code languages including but not limited to: Ada, ALGOL, Ateji PX, BASIC, C, C++, CLIPPER 5.3, CLEO, CLush (Lush), COBOL, Cobra, Common Lisp, Corn, Curl, D, DASL, Delphi, DIBOL, Dylan, eC, Eiffel, Factor, Forth, Fortran, Go, Haskell, Harbour, JAVA®, JOVIAL, LabVIEW, Nemerle, Objective-C, Pascal, Plus, ppC++, RPG, Scheme, Smalltalk, ML, Turing, Urq, Visual Basic, Visual FoxPro, Visual Prolog, WinDev, X++, XL, Z++and so on. Other types of artifacts are also contemplated including but not limited to catalog data, (e.g,. a list of zipcodes, Server Selection Policies-rules on what types of servers can host this database and so on. Moreover, although creation of a common model has been described herein in the context of a relational database management system, those of skill in the art will appreciated that the concepts described herein can also be applied in an object-oriented environment.

Because all the different types of heterogeneous artifacts can exist in a single project and/or information therefrom are added to a common model, design time tools including but not limited to auto-completion tools, refactoring tools and automated build and deployment tools can operate on a single project that includes heterogeneous artifacts and/or information derived therefrom and can provide comprehensive design time information that formerly was not available. For example, Microsoft's IntelliSense® provides developer support including automatically completing symbol names, providing internal documentation and disambiguation for variable names, functions and methods using reflection. Microsoft's IntelliSense® provides a convenient way to access descriptions of functions, such as for example, providing parameter lists for functions. It can speed up software development by reducing the amount of name memorization and keyboard input needed. It can reduce the need to refer to external documentation because interactive documentation on symbols including variables and functions in the active scope can appear dynamically during programming (e.g., in the form of tooltips).

Because IntelliSense® relies on accessing an automatically generated in-memory database of classes, variable names and other constructs defined in or referenced by the application being edited, adding the heterogeneous artifacts and/or information derived therefrom to the common model from which the database is generated, enables IntelliSense® to provide more comprehensive information to the developer.

Similarly, refactoring tools can provide more comprehensive results because the common model includes heterogeneous artifacts that previously had to be separated into different projects. Thus refactoring can be applied to a more inclusive universe. For example, if a variable name is changed from “name1” to “name2”, name1 will be changed to name2 in T-SQL statements and XSD files and in program code. The references including but not limited to references in program code (e.g., C#/VB.NET code, etc.) can be shown in a single common refactoring dialog. Refactoring into the XSD can occur for example, if an XML schema collection name is changed. In that case the XSD and referencing xml table columns might need to be altered.

Similarly, build and deployment tools that operate within the context of the IDE can provide more comprehensive results because the universe on which they operate is more inclusive.

FIG. 1 b illustrates another example of a system 101 for supporting creation of a deployment database of heterogeneous database artifacts from the command line. All or portions of system 100 may reside on one or more computers such as the computers described below with respect to FIG. 3. All or portions of system 100 may reside on one or more software development computers such as the computers described below with respect to FIG. 4. System 101 or portions thereof may be provided as a stand-alone system or as a plug-in or add-in.

System 101 may include one or more of a computer 102 comprising: a processor such as processor 142, a memory such as memory 144, and one or more modules such as module 109, etc. for supporting creation of a deployment datastore of heterogeneous artifacts from the command line. Other components well known in the arts may also be included but are not here shown. It will be appreciated that one or more modules such as module 109, etc. can be loaded into memory 144 to cause one or more processors such as processor 142 to perform the actions attributed to the one or more modules for supporting creation of a deployment datastore of heterogeneous artifacts from the command line.

In operation, in response to input from the command line 126, the artifacts including but not limited to T-SQL artifacts 118, VB.NET/C# artifacts 120, XSD artifacts 122 and/or other artifacts 124 can be received by software that builds executable programs and libraries from source code, (e.g., MSBUILD, etc.). A common model 110 can be created therefrom by module 109. A deployment artifact datastore 126 and a deployment plan (not shown) that includes all the components represented by the common model including heterogeneous database artifacts can be generated.

FIG. 2 b illustrates an example of a method 200 for providing support for heterogeneous artifacts in a single project in accordance with aspects of the subject matter disclosed herein. The method described in FIG. 2 b can be practiced by a system such as but not limited to the one described with respect to FIG. 1 a and/or by a system such as but not limited to the one described with respect to FIG. 1 b. Some of the actions described below can be optional. Some of the actions described below can be executed in a sequence that differs from that described below.

At 202 a module that provides support for heterogeneous artifacts in a single project can receive an artifact. As described more fully above, the received artifact can be a T-SQL artifact, a program code artifact, an XSD artifact or other artifact. At 204, as described more fully above, the artifact can be converted into a format compatible with a common model. Information derived from the artifact can be added to the common model. At 206 information from the common model can be used to provide design time information for interactive programming activities including development of program code or build and deployment tasks. At 210, information derived from heterogeneous artifacts can be displayed in an IDE. At 208, information from the common model can be accessed from the command line to generate a deployment plan at 212.

Example of a Suitable Computing Environment

FIG. 4 illustrates an integrated development environment (IDE) 600 and Common Language Runtime Environment 602. An IDE 600 may allow a user (e.g., developer, programmer, designer, coder, etc.) to design, code, compile, test, run, edit, debug or build a program, set of programs, web sites, web applications, and web services in a computer system. Software programs can include source code (component 610), created in one or more source code languages (e.g., Visual Basic, Visual J#, C++. C#, J#, Java Script, APL, COBOL, Pascal, Eiffel, Haskell, ML, Oberon, Perl, Python, Scheme, Smalltalk and the like). The IDE 600 may provide a native code development environment or may provide a managed code development that runs on a virtual machine or may provide a combination thereof. The IDE 600 may provide a managed code development environment using the .NET framework. An intermediate language component 650 may be created from the source code component 610 and the native code component 611 using a language specific source compiler 620 and the native code component 611 (e.g., machine executable instructions) is created from the intermediate language component 650 using the intermediate language compiler 660 (e.g. just-in-time (JIT) compiler), when the application is executed. That is, when an IL application is executed, it is compiled while being executed into the appropriate machine language for the platform it is being executed on, thereby making code portable across several platforms. Alternatively, in other embodiments, programs may be compiled to native code machine language (not shown) appropriate for its intended platform.

A user can create and/or edit the source code component according to known software programming techniques and the specific logical and syntactical rules associated with a particular source language via a user interface 640 and a source code editor 651 in the IDE 600. Thereafter, the source code component 610 can be compiled via a source compiler 620, whereby an intermediate language representation of the program may be created, such as assembly 630. The assembly 630 may comprise the intermediate language component 650 and metadata 642. Application designs may be able to be validated before deployment.

The various techniques described herein may be implemented in connection with hardware or software or, where appropriate, with a combination of both. Thus, the methods and apparatus described herein, or certain aspects or portions thereof, may take the form of program code (i.e., instructions) embodied in tangible media, such as floppy diskettes, CD-ROMs, hard drives, or any other machine-readable storage medium, wherein, when the program code is loaded into and executed by a machine, such as a computer, the machine becomes an apparatus for practicing aspects of the subject matter disclosed herein. In the case of program code execution on programmable computers, the computing device will generally include a processor, a storage medium readable by the processor (including volatile and non-volatile memory and/or storage elements), at least one input device, and at least one output device. One or more programs that may utilize the creation and/or implementation of domain-specific programming models aspects, e.g., through the use of a data processing API or the like, may be implemented in a high level procedural or object oriented programming language to communicate with a computer system. However, the program(s) can be implemented in assembly or machine language, if desired. In any case, the language may be a compiled or interpreted language, and combined with hardware implementations.

While the subject matter disclosed herein has been described in connection with the figures, it is to be understood that modifications may be made to perform the same functions in different ways.
